Established in 1939 as the Engineering Supply Company, Mayline has come a long way from its expertise in drafting tables, blueprint files and straightedges. The war years capitalized on their high quality and precision manufacturing for providing highly accurate navigational and mapping accessories for all branches of the military.

Though still a market leader in manual drawing (they invented the straightedge) and large format filing, Mayline has moved to the forefront of office ergonomics. The Mayline Group now includes Tiffany Industries, Kwik File and Mayline products.
